Proper new belt
 

Can anyone tell me the proper belt size for my cub cadet #70 to drive the 38 inch 3 spindle rotary mower deck (1963 series mower deck). I don't think I've ever had the correct size on so I not sure replacing it with the same is the right move. Thanks.

Is it a cast end deck or the one that does not have a cast ends on it? What type mule drive? Got any pix?

The deck has cast ends. I'm not sure how to identify what mule drive I have and I don't know how to load pictures, sorry. Using a downloaded cub cadet parts catalog # TC-103 I have the description. It is a hitch and drive unit and a main frame and knife unit (pages 66 and 67).

With a Model 70 Tractor, and a 38" 3 spindle deck with Cast Iron Ends, the chart says Drive Belt IH-473462-R4.

Thank you very much for the information. This site has been very helpful to me through the years and I'm glad I checked as the old belt was an incorrect size.
